We can use Active Objects in plugins, but which environment is suitable for it?
I propose that plugins with AO are for own Jira Server and it doesn’t work on Jira cloud, isn’t it?
We don’t have direct access for Jira Cloud DB, and it looks strange to connect from Cloud to some real DB on some external server.
Please help with understanding.
Yes, active objects are for server only. For exactly the reasons you suspect.
The closest equivalent in cloud is Hosted data storage: https://developer.atlassian.com/cloud/jira/platform/storing-data-without-a-database/
